The biggest cheerleader for potty training

Our whole family has been trying to be supportive of S potty training. Everyone has been really sweet. Her biggest supporter was a bit of a surprise. M has been very, very enthusiastic about her going in the potty. At the surface, it would seem weird that an 8 year old boy would be so excited at her potty success. But, consider this. M has a gumball machine filled with m&ms. Every time S goes in the potty successfully, I give her a nickel, dime, or quarter to put in the machine to get the M&Ms. M is beyond thrilled at how well she's doing with the potty.
